Формы создания/редактирования зон, устройств и правил автоматизации
ZoneFormScreen/DeviceFormScreen/AutomationRuleFormScreen — одна форма на создание и редактирование, показ ошибок валидации Laravel (422) по полям. Списки зон/устройств/правил дополнены FAB "добавить", свайпом/меню удаления и переходом в форму по тапу — всё только для owner (RBAC), viewer видит те же списки в режиме только чтения. Опции дропдаунов (типы устройств, датчики/актуаторы, capabilities) берутся из данных бэкенда, не хардкодятся.
